to send signals through the body when you touch something hot
yes the nerves are important.
cranial nerves.
Yes and no. There are nerves that innervate your skin and bones and meningeal coverings as well as the nerves that convey all of the input from your special sense organs but there are no "proper" nerves in your brain. In other words, your brain cannot feel anything itself. It can only interpret what other parts of your body are feeling.
There are close to 45 miles of nerves running from head to toe in the body. There are 43 pairs of nerves in this system.
The brainstem has nerves which extend outward to supply structures located mostly in the head and neck. These are called the cranial nerves.
Cranial nerves are a group of 12 pairs of nerves that arise directly from the brain and brainstem, rather than from the spinal cord. These nerves are responsible for providing motor and sensory innervation to structures of the head and neck, as well as certain viscera. They are important for functions like facial expression, eye movement, taste sensation, and hearing.
The nerves that originate in the brain and carry messages to and from structures in the head and neck are known as cranial nerves. There are 12 pairs of cranial nerves, each with specific functions related to sensory and motor control in the head and neck region. These nerves play crucial roles in activities such as vision, hearing, taste, and facial movements.
The head, axon and the nerve endings
Peripheral nerves may refer to the head and torso. The peripheral nerves carry information from the spinal cord to the rest of the body as well as information to and from the brain.
no, they are not, we are taking this test now haha
There are TONS of nerves in the head, but the main ones people are required to learn in college level anatomy courses are the 12 cranial nerves. Wikipedia has an article that lists them all and their function: http://en.wikipedia.org/wiki/Cranial_nerves
Cranial nervesCranial Nerves only originate in the brain and carry messages to and from structures in the head and neck.
